"The new Williams appears to be a good step forward over last year's car.

"There is a lot of good detail work on it. On the front wing, they have eased back on some of the very complex detail of the vortex generators around the endplates, which last year was probably too detailed. And in general it looks like a sound downforce-producing package.

"The front wing pillars have been moved forward, so they lean back towards the front wing. That's a good idea - it gives the airflow coming off the pillars more time to settle down before it gets to the turning vanes under the chassis.

"The downforce-producing devices on the front brake ducts are very detailed and the sidepods are very well undercut.

"Their ultra-low gearbox means there is very little airflow blockage at the rear of the car. There is just a lot of very good basic engineering on it and I would expect that they have made significant progress."

at 32 second, look at the radiator.at 54 sec look at their pushrod rear suspention and tiny tiny gear box. Directly behind the Outlet of the radiator hot air is madelike a doubel floor diffuser... what is this...????

this is going to beat the grid, I am convinced. This will perhaps threaten Red Bull. Looking forward to see if they have drivers to take this car to the top steps of the podiums multiple times....

Williams is still racing the Sam Michael's child. Good to see that they have good conviction on the result drawn previously. It is about the time that Williams beat fake Red Bull group. Beat them Beat them fair and square. ohh... I can't wait...

'While it should be obvious to everyone that Caterham's cover is illegal, opinions about the Williams solution conceivably could be divided. Whiting explains that ruling it legal would be an error in reasoning: "The side walls of the duct must be vertical and must not unify converge at the top. We do not want even a hint of a tunnel. Any cover, closed or open, is in violation."

The rule body knows very well what the result of a legal ruling would be: the whole duct would be covered. A tiny slot would suffice to circumvent the rule, and it would be in total opposite of the intent of the rule. [Edit: According to Autosport earlier today, Brawn said that Merc had asked FIA about such a solution during the winter, and were told it would be illegal]. Coughlan has been informed by the FIA.'
